Goldeneye (duck)
Template:Short description Template:Automatic taxobox
Bucephala is a genus of diving ducks found in the Northern Hemisphere.
Taxonomy
The genus Bucephala was introduced in 1858 by American naturalist Spencer Baird with the bufflehead as the type species.[1][2] The genus name is derived from Ancient Greek Template:Wikt-lang Script error: No such module "lang"., meaning Template:Gloss, from Script error: No such module "lang". Template:Gloss, and Script error: No such module "lang"., Template:Gloss, a reference to the crest of the bufflehead making its head look large.[3]
The bufflehead was formerly treated as the only member of the genus (sometimes unnecessarily changed to Charitonetta) while the goldeneyes were incorrectly placed in Clangula (as Clangula americana), the genus of the long-tailed duck, which at that time was placed in Harelda.[4] It may yet be correct to recognise two genera, as the bufflehead and the two goldeneyes are well diverged. In this case, Bucephala would be restricted to B. albeola and the name Glaucionetta (Stejneger, 1885) resurrected for the goldeneyes.
Species
The three living species are:[5] Template:Species table

- Bucephala cereti (Sajóvölgyi Middle Miocene of Mátraszõlõs, Hungary - Late Pliocene of Chilhac, France)[6]
- Bucephala ossivalis (Late Miocene/Early Pliocene of Bone Valley, United States),[7] which was very similar to the common goldeneye and may even have been a paleosubspecies or direct ancestorScript error: No such module "Unsubst".
- Bucephala angustipes (Early Pleistocene of central Europe)[8]
- Bucephala sp. (Early Pleistocene of Dursunlu, Turkey)[9]
Bucephala fossilis (Late Pleistocene of California, United States) is now considered an extinct subspecies of the Bufflehead.[10]
